In februar 2008 i was in Munich/Germany to visit the VOLVO SportsDesign FORUM on Ecodesign.The most impressive speech (for me quite influential) was the one of Michael Braungart, CEO of EPEA GmbH and MBDC McDonough Braungart Design Chemistry, L.L.C. talking about cradle to cradle design. He is working and consulting on intelligent, aesthetic and eco-effective design, "holistic good design".
